This is the follow-up work to support cluster scheduler. Previously
we have added cluster level in the scheduler for both ARM64[1] and
X86[2] to support load balance between clusters to bring more memory
bandwidth and decrease cache contention. This patchset, on the other
hand, takes care of wake-up path by giving CPUs within the same cluster
a try before scanning the whole LLC to benefit those tasks communicating
with each other.
[1] 778c558f49a2 ("sched: Add cluster scheduler level in core and related Kconfig for ARM64")
[2] 66558b730f25 ("sched: Add cluster scheduler level for x86")
Change since v3:
- fix compile error when !CONFIG_SCHED_CLUSTER, reported by lkp test.
Link: https://lore.kernel.org/lkml/20220608095758.60504-1-yangyicong@hisilicon.com/
Change since v2:
- leverage SIS_PROP to suspend redundant scanning when LLC is overloaded
- remove the ping-pong suppression
- address the comment from Tim, thanks.
Link: https://lore.kernel.org/lkml/20220126080947.4529-1-yangyicong@hisilicon.com/
Change since v1:
- regain the performance data based on v5.17-rc1
- rename cpus_share_cluster to cpus_share_resources per Vincent and Gautham, thanks!

Add per-cpu cluster domain info and cpus_share_resources() API.
This is the preparation for the optimization of select_idle_cpu()
on platforms with cluster scheduler level.

For platforms having clusters like Kunpeng920, CPUs within the same cluster
have lower latency when synchronizing and accessing shared resources like
cache. Thus, this patch tries to find an idle cpu within the cluster of the
target CPU before scanning the whole LLC to gain lower latency.
Note neither Kunpeng920 nor x86 Jacobsville supports SMT, so this patch
doesn't consider SMT for this moment.
Testing has been done on Kunpeng920 by pinning tasks to one numa and two
numa. On Kunpeng920, Each numa has 8 clusters and each cluster has 4 CPUs.
With this patch, We noticed enhancement on tbench within one numa or cross
two numa.

Some minor nits about the name of "sd_share_id".
It is not quite obvious what it is.
Maybe something like sd_lowest_cache_id to denote
it is the id of lowest shared cache domain between CPU.
Otherwise the patch looks good to me. You can add

Yicong,
Have you tried any workload where tasks don't share data
with each other but have sleep/wakeup? That's the case
where we actually want to spread the tasks out among the clusters
to void contention for L2 cache.
Will be nice to make sure there's no regression there for
such workload.
Code itself looks good.

guess there isn't a way to universally win in term of the modifcation of
scheduling policies. The good news is that as long as LB is still there,
tasks still get a good chance to spread if they stop talking to each other
again and again after a small talk.
if tasks do like spreading but keep in constant touch with each other, we
may have to interfere with them from userspace by openMP, numactl or
taskset etc. as WAKE_AFFINE is always an enemy for this requirement.

Any certain workload you'd like me test? I'm willing to do :)
I've tested this patch with MySQL as well (like in v2). This won't hurt
the MySQL case with SIS_PROP but observed some improvement with SIS_UTIL
posted in [1]. We leverage the nr to suppress redundant scanning in the
current approach and seems SIS_UTIL is more efficient in this case.

Thanks for the suggestion! Since Vincent and Gautham have suggested this in v1 [1], I'd like
to wait a bit before changing to this to see if they have any comment.

Thanks for the numbers. SIS_UTIL will keep off migrations off the cluster
that doesn't really improve overall utilization. We have higher chance that
L2 cache is warm. So it makes sense that we see a bit
better performance there.

Maybe I understand it incorrectly, here we changed the value of nr. Then if
we did not find any idle CPU in the cluster, nr is set to 0. Then in the LLC scan,
since there is 'if (--nr <= 0)', the LLC scan terminates.
Is the policy like: if we can not find one idle CPU in the cluster, we give
up scan for one in the LLC?

May I know the reason to change this? I thought this could be a seperate patch.

We're still scanning in the LLC since cluster is within the LLC (on Kunpeng 920 cluster cpus
share L3 Tag and on Jacobsville cluster cpus share L2, while on both platform LLC should be
the L3 cache). So if we've run out of nr we should stop scanning the rest of LLC as well

scan_cluster() may run out of nr (on Kunpeng 920 there're 4 cpus in one cluster and nr will be at least 4 with
SIS_PROP) and we cannot stop scanning correctly without this change. So the change should be in this patch.

So when nr reaches 0, the original loop could not stop. Thanks for the explanation.

Hello Yicong,
I replied to the v3 of the series by mistake!
(https://lore.kernel.org/lkml/0b065646-5b05-cbdb-b20c-e1dfef3f4d79@amd.com/)
But rest assured all the analysis discussed there was done with
the v4 patch series. I'll add the same observations below so we
can continue discussion on v4.
We are observing some serious regression with tbench with this patch
series applied. The issue doesn't seem to be related to the actual
functionality of the patch but how the patch changes the per CPU
variable layout.
Discussed below are the results from running tbench on a dual
socket Zen3 (2 x 64C/128T) configured in different NPS modes.
NPS Modes are used to logically divide single socket into
multiple NUMA region.
Following is the NUMA configuration for each NPS mode on the system:
NPS1: Each socket is a NUMA node.
Total 2 NUMA nodes in the dual socket machine.
Node 0: 0-63, 128-191
Node 1: 64-127, 192-255
NPS2: Each socket is further logically divided into 2 NUMA regions.
Total 4 NUMA nodes exist over 2 socket.
Node 0: 0-31, 128-159
Node 1: 32-63, 160-191
Node 2: 64-95, 192-223
Node 3: 96-127, 223-255
NPS4: Each socket is logically divided into 4 NUMA regions.
Total 8 NUMA nodes exist over 2 socket.
Node 0: 0-15, 128-143
Node 1: 16-31, 144-159
Node 2: 32-47, 160-175
Node 3: 48-63, 176-191
Node 4: 64-79, 192-207
Node 5: 80-95, 208-223
Node 6: 96-111, 223-231
Node 7: 112-127, 232-255
Benchmark Results:
Kernel versions:
- tip: 5.19.0-rc2 tip sched/core
- cluster: 5.19.0-rc2 tip sched/core + both the patches of the series
When we started testing, the tip was at:

Note: tbench results for 256 workers are known to have

seen for the data point can be safely ignored.
The behavior is consistent for both tip and patched kernel
across multiple runs of tbench.

data points with the machine running in NPS1 mode.
- Even on disabling HW prefetcher, the behavior remains consistent
signifying HW prefetcher is not the cause of the problem.
- Bisecting:
When we ran the tests with only Patch 1 of the series, the
regression was visible and the numbers were worse.

We further bisected the hunks to narrow down the cause to the per CPU
variable declarations.

The main reason for the regression seems to be the above declarations.
The regression seem to go away if we do one of the following:
- Declare sd_share_id and sd_cluster using DECLARE_PER_CPU_READ_MOSTLY()
instead of DECLARE_PER_CPU() and change the corresponding definition
below to DEFINE_PER_CPU_READ_MOSTLY().

Unfortunately, none of these are complete solutions. For example, using
DECLARE_PER_CPU_READ_MOSTLY() with both patches applied reduces the regression
but doesn't eliminate it entirely:

We are still trying to root cause the underlying issue that
brought about such drastic regression in tbench performance.

We would like some time to investigate this issue and root cause
the reason for this regression.

I think you meant that the regressions are due to the DEFINE_PER_CPU()
instances from the following hunk:

The System.map diff for these variables between tip vs tip +
cluster-sched-v4 on your test system looks as follows:
0000000000020520 D sd_asym_packing
0000000000020528 D sd_numa
-0000000000020530 D sd_llc_shared
-0000000000020538 D sd_llc_id
-000000000002053c D sd_llc_size
-0000000000020540 D sd_llc
+0000000000020530 D sd_cluster
+0000000000020538 D sd_llc_shared
+0000000000020540 D sd_share_id
+0000000000020544 D sd_llc_id
+0000000000020548 D sd_llc_size
+0000000000020550 D sd_llc
The allocations are in the reverse-order of the definitions.
That perhaps explains why you no longer see the regression when you
define the sd_share_id and sd_cluster per-cpu definitions at the
beginning as indicated by the following

Hi Prateek,
Seems my previous reply is in the wrong format so the server rejected it..just repost..
Thanks a lot for the test!

One significant difference I can see for now is that Kunpeng 920 is a non-SMT machine while Zen3
is a SMT machine. So in the select_idle_sibling() path we won't use sd_llc_shared. Since sd_share_id
and sd_cluster are inserted between sd_llc_id and sd_llc_shared which are both used in the path on
your test, I guess the change of the layout may affect something like the cache behaviour.
Can you also test with SMT disabled? Or change the layout a bit to see if there's any difference,
like:
DEFINE_PER_CPU(struct sched_domain __rcu *, sd_llc);
DEFINE_PER_CPU(int, sd_llc_size);
DEFINE_PER_CPU(int, sd_llc_id);
DEFINE_PER_CPU(struct sched_domain_shared __rcu *, sd_llc_shared);
+DEFINE_PER_CPU(int, sd_share_id);
+DEFINE_PER_CPU(struct sched_domain __rcu *, sd_cluster);
DEFINE_PER_CPU(struct sched_domain __rcu *, sd_numa);
DEFINE_PER_CPU(struct sched_domain __rcu *, sd_asym_packing);
I need to further look into it and have some tests on a SMT machine. Would you mind to share
the kernel config as well? I'd like to compare the config as well.
Thanks,
Yicong

looks like below are in another cacheline (for 64B cacheline)?
while previous sd_llc_id and sd_llc_shared are in the same.

As you can see the regression still exists. even with only first patch
of the series applied on top of the tip. Moving the declarations around
to top helps some cases but we are having troubles at the saturation
point with the move.

I've attached the kernel config used to build the test kernel

We are trying to debug the issue using perf and find an optimal
arrangement of the per cpu declarations to get the relevant data
used in the wakeup path on the same 64B cache line.
We'll keep you posted of out finding. Let me know if you need
anything else in the meantime.

Wonder if it will help to try keep sd_llc and sd_llc_size into the same
cache line. They are both used in the wake up path.

A check of perf c2c profile difference between tip and the move new declarations to
the top case could be useful. It may give some additional clues of possibel
false sharing issues.

We are still evaluating keeping which set of variables on the same
cache line will provide the best results.
I would have expected the two kernel variants - "tip" and the
"tip + both patches (Move declaration to top)" - to give similar results
as their System map for all the old variables remain the same and the
addition of "sd_share_id" and "sd_cluster: fit in the gap after "sd_llc".
However, now we see a regression for higher number of client.
This probably hints that access to "sd_cluster" variable in Patch 2 and
bringing in the extra cache line could be responsible for the regression
we see with "tip + both patches (Move declaration to top)"

Thank you for the suggestion. We are currently looking at perf counter
data to see how the cache efficiency has changed between the two kernels.
We suspect that the need for the data in the other cache line too in the
wakeup path is resulting in higher cache misses in the levels closer to
the core.
I don't think it is a false sharing problem as these per CPU data are
set when the system first boots up and will only be change again during
a CPU hotplug operation. However, it might be beneficial to see the c2c
profile if perf counters don't indicate anything out of the ordinary.

Would it be possible if any other frequent-written variables share
same cacheline with these per-cpu data causing false sharing? What
about making all these sd_* data DEFINE_PER_CPU_READ_MOSTLY?

thanks for the comment. If we've run out of nr the select_idle_cpu() will stop scanning as well,
so it's unnecessary to clear the mask of cluster cpus and just return.

Hello Abel,
Thank you for looking into this issue.
tl;dr
We have found two variables that need to be
co-located on the same cache line to restore tbench
performance.
As this issue is unrelated to the functionality of
the patch, it should not hold this patch series from
landing given the performance improvements seen on
systems with CPU clusters.
The results of our analysis are discussed in
detail below.

This indeed seems to be the case. I'll leave the
detailed analysis below.

Making all the sd_* variables DEFINE_PER_CPU_READ_MOSTLY or
placing all the sd_* variables on the same cache line doesn't
help the regression. In fact, it makes it worse.
Following are the results on different test kernels:
tip - 5.19.0-rc2 tip
(commit: f3dd3f674555 "sched: Remove the limitation of WF_ON_CPU on wakelist if wakee cpu is idle")
cluster - tip + both the patches of the series
Patch1 - tip + only Patch 1
align_first (Patch 1) - tip + only Patch 1 + all sd_* variables in same cache line
per_cpu_aigned_struct (Patch 1) - tip + only Patch 1 + all sd_* variables part of a per_cpu struct which is cacheline aligned

At this point it was clear that one or more sd_* variable needs
to be co-located with the per CPU variables in cache line starting
at 20540. We began moving variable out of the cache line one by one
to see which variable makes the difference as we found out that as
long as root_cpuacct_cpuusage and sd_llc_id are on the same cache
line, the results were equivalent of what we saw on the tip. As both
the variables seem to be accesses very frequently, access to one will
prime the cache line containing the other variable as well leading to
better cache efficiency.
Placing root_cpuacct_cpuusage, sd_llc_id, sd_share_id, sd_llc_shared
and sd_cluster on the same cache line, the results are as follows:

Chenyu's SIS_UTIL patch was merged today in the tip
(commit: 70fb5ccf2ebb "sched/fair: Introduce SIS_UTIL to search idle CPU based on sum of util_avg")
and seems to bring back performance to the same level
as seen on the tip used during our testing.
The system map of the tested configuration labelled "Custom Layout"
is as follows:

The System-map is however dependent on multiple factors
such as config options enabled, etc. which can change from
build to build.
Finding a permanent solution to the issue might take
some more time.
Meanwhile, as this is an issue unrelated to the
functionality of this patch, it should not block
the landing of this patch series.
Thank you everyone for your pointers and patience
during this debug.

The percpu variables seems won't be affected by the non-percpu variables as the
percpu section is already cacheline aligned. arm64's vmlinux.ld.S shows

Thanks for the data. It looks sufficient to illustrate the issue. I'm still a little curious that
is it specific on Zen 3? Since I cannot get the Zen 3 machine so I tried to reproduce this on the a
AMD 7742 (2 x 64C/128T) and an Intel 6148 (2 x 40C/80T) machine with your config based on tip/sche/core
of commit f3dd3f674555 "sched: Remove the limitation of WF_ON_CPU on wakelist if wakee cpu is idle".
With cluster's percpu definition patch(the worst case) the root_cpuacct_cpuusage and sd_llc_id are
separated but make little difference to the tbench.
